Plastic salad containers are often not recyclable due to the molding process that makes the plastic more brittle and harder to reuse. This process results in a different grade of plastic that is typically considered a contaminant and has little to no market value, making it unattractive for recycling centers to accept. However, some places do accept these containers despite their low value. To recycle plastic salad containers with Republic Waste, it is important to understand what plastics can and cannot be recycled. Republic Services provides guidelines for recycling various materials, including plastic bottles and jugs, cardboard, paper, and metal cans. They emphasize the importance of keeping recyclables free of food and liquid, and not placing them in containers or bags. Republic Services is also investing in innovative centers to better manage plastic recycling and put more recycled plastics back into use.

Plastic salad containers are often non-recyclable due to the moulding process
Salad containers are typically made with polyethylene thermoplastic (PET) using a process called thermoforming. This process involves heating the plastic and then shaping it into the desired form. While this process is efficient and cost-effective for producing containers, it results in a lower-grade plastic that is not as valuable or desirable for recycling.
In contrast, most plastic bottles and jugs undergo a different process called blow moulding, which results in a higher-grade PET. The different processes and grades of PET mean that staff at recycling centres have to manually separate the different types of plastic containers. This additional step requires time, labour, and cost, and can contaminate other recycled materials if not done properly.
Due to the challenges and costs associated with recycling plastic salad containers, many recycling centres do not accept them. However, a handful of places do accept these containers, despite their low to no value. Additionally, some companies offer specialised recycling boxes that can be filled and shipped back for proper recycling, ensuring that even these challenging plastics can be responsibly recycled.
To reduce the environmental impact of plastic salad containers, consumers can also take proactive steps. This includes choosing reusable options, avoiding products packaged in clamshells or other low-value plastics, and supporting companies that use compostable bioplastics or recyclable alternatives. Growing your own greens or buying fresh greens locally at farmers' markets are also great ways to reduce reliance on plastic salad containers.

Recycling plastic containers saves energy, water and reduces carbon emissions
Plastic salad containers are often not recycled due to the specific type of plastic they are made from and the processes required to recycle them. However, recycling plastic containers, in general, has significant benefits for the environment and can save energy, water, and reduce carbon emissions.
Firstly, recycling plastic containers saves energy. By using recycled materials, manufacturers can produce the same goods with less energy and expense. Recycled materials have already been refined and processed, so manufacturing from these materials is less energy-intensive than using raw materials. Recycled materials also reduce or eliminate the need to extract and process natural resources, which is labour-intensive and expensive. Recycling one pound of plastic salad containers could save around 3.35 kilowatt hours of energy.
Secondly, recycling plastic containers can help to reduce water usage. According to a report by "Eco-profiles of the European Plastics Industry", recycling one pound of plastic containers could save 2.5 gallons of water. This is in addition to the thousands of trees that are saved through paper recycling, which also reduces water usage.
Thirdly, recycling plastic containers can lead to a reduction in carbon emissions. Recycling one pound of plastic containers could result in a reduction of one pound of carbon dioxide emissions. This is especially important as plastic production contributes to global warming and carbon emissions.
In addition to these benefits, recycling plastic containers can also reduce waste hauling costs, improve workplace safety, and create space. Furthermore, recycling can reduce the need for landfill sites and incineration, which have negative environmental impacts.
While recycling is a great way to give plastic containers a second life, it is also important to reduce plastic consumption and properly dispose of plastic waste. Some ways to reuse plastic containers include using them for storage, creating decorations, or feeding and watering pets.

Recycling centres avoid plastic salad containers to prevent contamination
Plastic salad containers are often not recyclable, and many recycling centres avoid accepting them to prevent contamination. This is because the plastic used in these containers has undergone a molding process called thermoforming, which makes it more brittle and harder to reuse. This type of plastic is considered a contaminant and has little to no market value, making it unsuitable for recycling.
Salad containers are typically made with polyethylene thermoplastic (PET) using thermoforming. This process results in a different grade of PET compared to the PET used in plastic bottles and jugs, which undergo blow molding. The variation in the grade of PET means that staff at recycling centres must manually separate these different types of plastic containers.
The process of manually separating the different grades of PET is labour-intensive and increases costs for recycling centres. To avoid these additional costs and prevent contamination, many recycling centres choose not to accept plastic salad containers. However, a handful of places do accept these containers despite their low to no value.
It is important to note that recycling plays a crucial role in protecting the planet, and proper recycling practices can help keep valuable materials in the circular economy, reducing the strain on the environment. While plastic salad containers may not always be recyclable, there are alternative options to consider. Consumers can opt for reusable containers or purchase fresh greens locally at farmers' markets, bringing their containers for a zero-waste experience. Additionally, some companies offer recycling boxes that can be filled and shipped back for proper plastic sorting and recycling.

Plastic bags, wrappers and flexible packaging are too thin to be recycled
Plastic salad containers are often not recyclable. While recycling a pound of plastic clamshell containers could save a pound of carbon dioxide emissions, 2.5 gallons of water, and around 3.35 kilowatt hours, many recycling centers do not accept them. This is because the molding process that creates plastic salad containers makes the plastic more brittle, harder to reuse, and less valuable as a raw material. The plastic used in salad containers, polyethylene terephthalate (PET), undergoes thermoforming, a different process than the blow molding used for most plastic bottles and jugs. The different processes result in different grades of PET, and recycling centers must manually separate these types of plastic containers to avoid contamination, increased labor, and increased costs.
Now, regarding plastic bags, wrappers, and flexible packaging, while they are technically recyclable, they are often too thin to be recycled through most standard programs and facilities. These thin plastics, also called plastic film packaging, are typically stretchy and can get stuck in recycling equipment, requiring workers to shut down the machinery and remove them, wasting time and money. As a result, most recycling facilities are not equipped to handle these materials and do not accept them. However, some retail stores and drop-off centers have specialized bins for collecting plastic film packaging for recycling.
It is important to note that plastic bags, wrappers, and flexible packaging can be recycled differently than bottles and containers. While they should not be placed in curbside recycling bins, they can often be recycled at participating retail stores. This is because recycling is local, and there may be differences in the capabilities of recycling programs from town to town. Therefore, it is always essential to check with your local recycling entity to understand their specific guidelines and capabilities.
To promote the recycling of plastic bags, wrappers, and flexible packaging, individuals can take several steps. Firstly, it is crucial to reduce the use of disposable shopping bags by using reusable bags when shopping. Additionally, plastic bags can be reused for multiple shopping trips or repurposed for other purposes, such as trash liners or pet waste bags. By reducing, reusing, and properly recycling these materials, we can lessen their negative environmental impacts and promote the continued use of plastic resources.

Republic Services' Polymer Centre will help manage the plastics stream
Plastic salad containers are often not recyclable. While recycling centres accept a variety of rigid plastic containers, the molding process that plastic salad containers undergo makes the plastic more brittle, harder to reuse, and less valuable as a raw material. This means that recycling centres have to manually separate these types of containers, increasing labour and costs.
Republic Services, a leader in the environmental services industry, has recently opened its first Polymer Centre in Las Vegas, with a second facility expected to open in Indianapolis in late 2024. The Polymer Centre will help manage the plastics stream through an integrated process from curbside recycling pickup to production and delivery of high-quality recycled content for consumer packaging.
The Polymer Centre will produce 100 million pounds of recovered resin product per year, enabling greater circularity for plastics and helping meet the growing demand for recycled materials for use in sustainable packaging. The centre will process plastic bottles, jugs, and containers collected from homes and businesses to produce recycled PET (rPET) flake and colour-sorted HDPE and polypropylene ready for use in new sustainable packaging.
Through innovation and investment in its new Polymer Centres, Republic Services is advancing circularity for plastics. The company's strategy has changed the circular economy narrative and demonstrated that market-based circular solutions are viable.
